Which climate factor/s or soil condition/s effect/s the end of growing season for plants? We have investigated the effect of climate factors on the start of the growing season (SGS) for deciduous plants (i.e. Betula pubescens) and find that the SGS of B. pubescens is dependent on air temperature and the plants have a acclimatised to the temperature change from winter time to spring time. But we don't find any effect of air temperature on the end of growing season for these plants. Does anybody have any idea which factor/s or conditions can influence the end of growing season by deciduous plants?
Temperature and/or photoperiod are driving factors of phenological events depending on species . Bud set, however, is presumably more sensitive to photoperiod and edaphic factors.
Dear Jonathan, Dear Lahcen, Dear Maggie,
thank you very much for your interesting replies. I agree with Maggie. I worked with several plant species from the familie Ericaceae in Mediterranean area. During the end of growing season, the plants don't have light or temperature stress. But they have definitely available water stress. But i dont know, if we can assume this for the deciduous species in temperate areas of Northern Europe. Usually, the plants in Northern Europe dont have water stress. I guess, in such areas, the air or soil temperature can have an important influence on the EGS.
ps. Many thanks to Maggie for the very interesting paper.
